Yeah, if it's clearly visible the remote's good to about 30-35. That's as far as I'd ever want to put it though.
All the problems i have had with my foxpro have been due to exhausted batteries. Fresh batteries snaps it right out of it. Can't help with the range issue. About the farthest out my caller has been is 40-50 yards. i like to plant my stuff and get on stand as quickly as I can. Often times the caller is just a few feet from where I'm sitting.
I usually dont put the call very far from where I'm set up either, maybe 15-20yds or less. I like to try & get them in as close as possible and shotgun em if I can - plus then I can hear it easily too. But I was having problems with my Power Dogg even at that range and with new batteries. I dont think I've ever setup my FP more than 50yds away, but I've never had an issue with the remote range. I also use my quiver critter rabbit decoy almost every time too, so I put it and the call about 5ft from each other with the decoy in a little clear spot and then the caller hidden in a bush, tuft, stump, etc. I love that decoy and swear by that little bunny, it has drawn more than a few kyoats into their demise.
